100x150x13 NBR AO/TC GRN® Double Lip Radial Shaft Oil Seal

100x150x13 NBR AO/TC GRN® Double Lip Radial Shaft Oil Seal

100x150x13 NBR AO/TC GRN® is a double-lip radial shaft oil seal manufactured from NBR - Nitrile Butadiene Rubber.

Its installation dimensions are 100x150x13 mm: 100 mm nominal shaft diameter, 150 mm housing bore diameter and 13 mm seal width.

The AO/TC configuration combines a spring-loaded primary sealing lip with an additional dust lip.

What Does 100x150x13 Mean?

The designation 100x150x13 mm defines the three principal installation dimensions:

100 mm - nominal shaft diameter
150 mm - nominal housing bore diameter
13 mm - seal width

All three dimensions should match the installation.

For complete identification, the NBR material and AO/TC double-lip configuration should also be verified.

AO/TC Double-Lip Design

The AO/TC design incorporates two functional lips.

The primary sealing lip operates dynamically against the rotating shaft surface. A garter spring helps maintain radial contact between the elastomer sealing edge and the shaft counterface.

The additional dust lip forms a secondary protective barrier toward the external side of the seal and helps reduce the ingress of contamination into the primary sealing area.

This construction distinguishes the AO/TC version from corresponding single-lip radial shaft oil seals.

Spring-Loaded Primary Sealing Lip

The primary dynamic sealing lip is supported by a garter spring.

The spring helps maintain contact between the sealing edge and the shaft counterface during operation.

The principal dynamic sealing interface consists of:

primary sealing lip + garter spring + shaft counterface

The condition and surface finish of the shaft in the sealing area are therefore important for proper seal operation.

Additional Dust Lip

The second lip performs a protective function.

It helps reduce the ingress of:

dust
dirt
small particles
external contamination

Its purpose is to help protect the area where the primary sealing lip operates.

The dust lip does not replace the primary dynamic sealing lip - each lip performs a separate function.

NBR Nitrile Rubber

The 100x150x13 AO/TC GRN® oil seal is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used for radial shaft oil seals and is compatible with many commonly used mineral oils, lubricating greases and industrial lubricants.

Actual compatibility should always be verified against the specific medium, additives, temperature and operating conditions.

Why Is the AO/TC Design Important?

The dimensions 100x150x13 mm alone do not completely define the oil seal.

Radial shaft oil seals with identical dimensions can differ in material and sealing-lip configuration.

For this version:

NBR - identifies the elastomer material
AO/TC - identifies the double-lip configuration
GRN® - identifies the product brand

The complete designation 100x150x13 NBR AO/TC GRN® therefore provides more precise identification than the dimensions alone.

100x150x13 AO/TC vs Single-Lip Oil Seal

100x150x13 NBR AO/TC GRN®:
spring-loaded primary sealing lip
additional dust lip

Single-lip design:
spring-loaded primary sealing lip
no additional dust lip

Therefore, identical dimensions do not automatically confirm full interchangeability.

How to Select 100x150x13 NBR AO/TC GRN®

For correct identification, verify:

Shaft Diameter: 100 mm
Housing Bore Diameter: 150 mm
Width: 13 mm
Material: NBR
Design: AO/TC
Configuration: Double lip
Brand: GRN®

Complete identification:

100x150x13 + NBR + AO/TC + GRN®

helps distinguish this version from other radial shaft oil seals with the same installation dimensions.

FAQ

What are the dimensions of the 100x150x13 NBR AO/TC GRN® oil seal?

The dimensions are 100x150x13 mm: 100 mm shaft diameter, 150 mm housing bore diameter and 13 mm width.

What shaft diameter is the 100x150x13 oil seal designed for?

It is designed for a nominal 100 mm shaft diameter.

What housing bore is required?

The nominal housing bore diameter is 150 mm.

Is the 100x150x13 NBR AO/TC GRN® oil seal double lip?

Yes. The AO/TC design combines a spring-loaded primary sealing lip with an additional dust lip.

What does AO/TC mean?

For this GRN® version, AO/TC identifies a double-lip radial shaft oil seal design with a spring-loaded primary sealing lip and an additional dust lip.

What is the purpose of the garter spring?

The garter spring helps maintain radial contact between the primary sealing lip and the shaft counterface.

What material is the 100x150x13 GRN® oil seal made from?

It is manufactured from NBR - Nitrile Butadiene Rubber.

Can any 100x150x13 oil seal be used as a replacement?

Not automatically. The dimensions, material and sealing-lip configuration should all be verified. This version is NBR with an AO/TC double-lip design.
